DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an excrement holding device to be mounted on a stoma constructed by surgical operation on the surface of a human body.

[0002]

2. Description of the Related Art A person having a stoma on the body surface due to a disease of an organ related to the excretion mechanism of the human body, making it impossible to excrete directly from the anus or urinary organ, or a stoma on the body surface due to other diseases. In order to process the excretions such as stool, urine, and body fluid discharged from the excretion holes, the person who constructed the There must be. There are various types of this excrement storage device, but basically a bag body for storing excrement in a skin portion having an opening at the center and having an adhesive skin protective agent layer on one surface. The skin is attached to the body surface with an adhesive skin protective agent layer so that the opening is along the excretion hole.The excrement that comes out of the excretion hole passes through the opening of the skin. To be housed in a bag. When attaching the brace around the excretion hole with the skin, if the excretion hole protrudes even slightly from the human body surface, the problem arises because the tip opening of the excretion hole protrudes into the bag from the opening of the skin. However, in the case of a so-called depression type excretion hole where the excretion hole is lower than the surface of the human body, the excretion stays on the body surface because the tip of the excretion hole does not protrude toward the bag from the skin opening. However, there is a possibility that invasion into the adhesive skin protective agent layer of the skin contact portion sometimes causes inconvenience such as skin swelling and excretion leakage due to peeling of the adhesive skin protective agent layer. In order to improve this point, a so-called convex plate made of a semi-rigid material and having a portion protruding toward the surface of the human body is provided on the skin side of the skin portion, and the convex portion is adhered and fixed to the surface of the human body. It has been practiced to push the excretion hole toward the surface of the human body by a pressing force exerted on the periphery of the excretion hole. FIG. 4 is a cross-sectional view of one example. Reference numeral 1 denotes a skin portion, which has an opening 2 in the center portion, a portion 3 protruding toward the skin side around the center portion, forms a convex plate structure, and has an adhesive on the entire surface on the skin side. The skin protective agent layer 4 is provided. A ring-shaped flange 5 is fixed to the surface of the skin portion 1 opposite to the skin side, that is, the non-skin side, and the flange 5 has an opening 6 corresponding to the opening 2 and a ring-shaped outer peripheral edge. A fitting portion 7 is provided. Reference numeral 8 denotes a bag body, a ring-shaped flange 10 is fixed around the opening 9, and the flange 10 can fit with the opening 11 corresponding to the opening 9 at the center thereof and the fitting portion 7 at the outer peripheral edge. A ring-shaped fitting portion 12 is provided. The bag 8 is integrated with the skin portion 1 by connecting the fitting portions 7 and 12, and the discharged excrement is stored in the bag, and the bag 8 is removed by removing the fitting portions 7 and 12. The excrement inside can be treated. This type of excrement storage equipment can easily treat excrement and can be used repeatedly, and is awarded as a so-called two-piece type equipment. In this two-piece type orthosis, it is necessary to attach / detach the fitting part of the skin part and the fitting part of the bag, but when attaching / detaching both fitting parts, it is painful if pressure is applied to the excretion hole. It is necessary to insert and remove a finger on the back side of the fitting portion 7 on the skin side to support the fitting portion from below to perform the attaching / detaching operation. In this case, the convex plate structure of the skin portion is hardly deformed because it is formed of a semi-rigid material. If the gap 13 between the skin portion 1 and the flange 5 is small, a finger does not enter and the detachment operation is difficult. One way to increase the gap 13 is to use the skin 1 of the flange 5.
The flange 5 is attached to the skin portion 1 by welding, so that the angle of the fixed portion 14 of the flange 5 with respect to the skin portion 1 is large. When the end of the fixing portion 14 is welded to the skin 1, there is a great risk that a welding tool approaches the fixing portion 14 and damages the fixing portion 14 due to heat. A method of extending the flange 5 outward and making the fitting portion 7 far from the outer peripheral edge of the skin portion is also conceivable, but an increase in the outer diameter of the flange 5 also increases the outer diameter of the flange 10 of the bag body. This means that the entire brace becomes extremely large and the wearing feeling is poor. In addition, since the convex plate structure is not required for the non-depressed excretion hole,
It is preferable to attach the flange to the flat and flexible skin, in which case the finger is inserted with the help of the flexibility of the skin even if the gap between the body of the skin and the flange is somewhat narrow. It is easy to do so and there is no problem in the attaching / detaching operation. Therefore, the flange for the normal excretion hole and the flange for the depressed excretion hole must be considered as separate structures, and a structure common to both cannot be adopted, which increases the cost of the brace. Therefore, it is desirable that the structure of both flanges can be shared regardless of the excretion hole applied.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a device in which a skin portion having a convex plate structure and a bag body are easily detachable from a detachable brace, and which is common regardless of the excretion hole to be applied. It is an object of the present invention to provide an excrement holding device that can use the parts described above.

[0004]

In order to solve the above-mentioned problems, in the present invention, a skin portion having an opening corresponding to an excretion hole formed in a human body is fixed to a non-skin side of the skin portion.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.

FIG. 1A is a sectional view of an embodiment of the present invention.
B is a perspective view of the skin portion, and the same reference numerals are given to the same portions as those in FIG. The skin portion 1 is formed, for example, in a circular ring shape, has an opening 2 at the center corresponding to the excretion hole formed in the human body, and a portion protruding around the skin side, that is, the opening 2 on the side in contact with the body surface. An adhesive skin protective agent layer 4 is provided on the entire surface on the skin side, and a ring-shaped projection 16 is formed around the opening 2 on the surface on the non-skin side. The opening 6 of the first flange 5 is fixed to the tip 17 of the projection 16, and a fitting portion 7 is formed on the outer peripheral edge of the first flange 5 on the side opposite to the fixed side. It is configured to have flexibility. By fixing the first flange 5 to the tip 17 of the projection 16, the gap d between the back side of the fitting portion 7 of the flange 5 and the surface on the non-skin side of the skin portion 1 is particularly large. The second flange 10 has an opening 2,
It has an opening 11 corresponding to the opening 6, and a fitting portion 12 that fits with the fitting portion 7 of the first flange is formed on the outer peripheral edge. A bag 8 is provided on the non-skin side of the second flange 10.
Is fixed, and the bag body 8 has an opening 9 corresponding to the opening 2, the opening 6, and the opening 11.

The body of the skin 1 is advantageously made of a heat-sealable, semi-rigid plastic material such as polyethylene, ethylene-vinyl acetate copolymer, ethylene-methyl acrylate copolymer, etc. It is preferable that the main body of the skin is formed integrally with the same material. In this case, for example, injection molding can be used. However, the projections 16 may be made of a thermoplastic elastomer while the skin portion is made of a semi-rigid plastic material, and may be made elastic. As this thermoplastic elastomer,
SBS (polystyrene-polybutadiene-polystyrene), SIS (polystyrene-polyisoprene-polystyrene), SEBS (polystyrene-poly (ethylene-
Polystyrenes such as (butylene) -polystyrene) and SEPS (polystyrene-poly (ethylene-propylene) -polystyrene), polyolefins, vinyl chlorides, polyesters, polyurethanes, polyamides, and fluorines can be used. When the skin portion main body and the projection are formed of different materials, two types of insert molding used to make a plastic molded product of different materials are used.
A composite injection molding method such as molding of different materials can be used.
As the adhesive skin protective agent layer 4 of the skin portion 1, for example, a combination of a hydrophilic component (eg, karaya gum, citrus pectin) and a hydrophobic component (eg, polyisobutylene, styrene-based thermoplastic elastomer) can be used.

The same material can be used for the first and second flanges, for example, ethylene-ethyl acrylate copolymer, ethylene-vinyl acetate copolymer, ethylene-methyl acrylate copolymer, polyethylene, polypropylene, and chloride. Vinyl, ethylene-acrylic acid copolymer, ethylene-methacrylic acid copolymer,
There are chlorinated polyethylene and the like.

FIG. 2 is a sectional view showing a state in which the brace shown in FIG. 1 is mounted on the surface of a human body. 21 is a human body, and 22 is an excretion hole formed on the body surface. The brace is the opening 2 of the skin 1
Is attached along with the excretion hole 22 with the adhesive skin protective agent layer 4 of the skin portion, the protruding portion 3 of the skin portion 1 presses around the excretion hole 22, and as a result, the excretion hole 22
Is pushed out to the body surface even if it is of a depressed type. As shown in the figure, a finger is inserted between the non-skin side surface of the skin portion 1 and the back side of the fitting portion 7 of the first flange 5 to support the fitting portion 7 from the back side. By performing attachment / detachment between 7 and 12, the orthosis can be operated without exerting any pressing force on the body surface.

FIG. 3 is a cross-sectional view of a different embodiment of the first flange, and the same reference numerals are given to the same parts as in FIG. The inner part 31 of the flange 5 excluding the fitting part 7 is formed of a thermoplastic elastomer, and the inner part can be extended or deformed during the attaching / detaching operation between the first and second flanges. Becomes easier. As the thermoplastic elastomer, the same ones as those used when the above-mentioned projections are formed of the thermoplastic elastomer can be used, and the same composite injection molding method can be used as the molding method.
In this case, it is not necessary to form all of the inner part of the first flange except for the fitting part with the thermoplastic elastomer, and only a part thereof may be formed with the thermoplastic elastomer. For example, the portion of the first flange near the fixing portion to the skin portion may be formed of a thermoplastic elastomer in a ring shape, and the remaining portion may be formed of another material. The point is that at least a part of the inner portion of the fitting portion of the first flange has elasticity, elasticity, and flexibility during the attaching / detaching operation.

[0015]

According to the present invention, by providing a sufficiently large gap between the flange provided on the skin portion and the body of the skin portion, the attachment / detachment between the skin portion and the bag body can be achieved. Can be performed very easily and without causing any pain to the human body, and the structure of the flange itself can be commonly used for a normal excretion hole and a depression type excretion hole. It is sufficient to prepare two types of portions, one having no ring-shaped projection and one having a projection, which can reduce the manufacturing cost.
